Status: Common regular breeder and spring and fall migrant east, rare central.
Documentation: Specimen: HMM 2733, 2 May 1896 Giltner, Hamilton Co.
Taxonomy: No subspecies are recognized (Pyle 1997). This species and 10 others previously in Caprimulgus were moved to Antrostomus based on Han et al (2010).
Spring: Apr 13, 15, 18 <<<>>> summer
Arrival is in late Apr. The early date above was of one that hit a window 13 Apr 2018, recovered, and was released after photographs were taken (Elaine Bachel, personal communication).
Arrival is in late Apr. The only reports from the western half of the state, none well-documented, are of one in Perkins Co 6 May 1970 identified by size and wing length relative to the tail (Cortelyou 1970), one in Dawson Co 28 Apr 1935, the only local record (Kinch 1964), and one in McPherson Co 17 Jun 1972 (Cortelyou 1972). One was westerly near Gibbon, Buffalo Co 22 May 2001, and Whip-poor-will was considered a rare migrant in Hamilton Co in 1962 (Swanson 1962). This species is a casual migrant in eastern Colorado in May and Sep (Andrews and Righter 1992).
- High counts: 17 at Oak Glen WMA, Seward Co 26 May 2010, 14 at Indian Cave SP, Nemaha and Richardson Cos 12 May 2001, 14 at Oak Glen WMA 11 May 2017, and 14 there 30 May 2018.
Summer: Like Chuck-will’s-widow, documented nesting records are few, perhaps six in all. Most recent are of a nest with two eggs at Ponca SP, Dixon Co 16 May 2009 (Mollhoff 2016) and a nest with an egg and a chick photographed at Indian Cave SP, Richardson Co 3 Jul 2014.
Breeding or territorial birds occur in oak-hickory forest in the southeast, along the lower Platte River Valley, and along the lower Niobrara River Valley. The species is often absent in woodland habitat that is intensively grazed (Youngworth 1958), and in dense, closed-canopy forest, preferring relatively open woodland habitats (Cink et al 2017).
In the Niobrara River Valley, it occurs west to extreme eastern Cherry Co (Brogie and Mossman 1983); there were multiple reports from Smith Falls SP, Cherry Co 19 May-19 Jun 2015-2017, and one was heard at Berry Bridge Campground, Cherry Co, 26 May 2017. One was heard along Highway 12 in extreme western Keya Paha Co 7 May 2002, two were in eastern Keya Paha Co 12 Jun 2014, and 1-4 were counted at each of eight stops along Ponca Creek on Highway 12 in Boyd Co 28 Jun 2012.
Although nesting is undocumented at NNF Bessey, Thomas Co, there have been recent reports during the nesting season suggestive of nesting; these are 28 Jun 2011, 27 Jun 2013, and 3 Jul 2015. Bruner et al (1904) listed this species as occurring rarely in Thomas Co, but without dates; these may have been migrants.
It occurs regularly in the Platte River Valley only west to the Morse Bluff area of northern Saunders Co, where 14 were counted 17-21 May 1995 (Silcock 1995); it was unrecorded in Hall Co by Lingle (1994), although Mollhoff (2001) showed a “possible” breeding record in Hall Co in the period 1984-89.
On the Big Blue River, it occurs during the nesting season north to Seward Co, where it was first reported at Oak Glen WMA 25 Jun 1995; a good tally of 16 was made there 15 Jul 2006. On the Big Nemaha River, it occurs west to Pawnee Co (Bennett 1974, Johnsgard 1980), and there are a few reports from the Little Blue River Valley in Jefferson Co, where two were near Fairbury 21 Jul 2011 and one at Rock Glen WMA 8 May 2012.
- Breeding Phenology:
Eggs: 15 May-3 Jul
Nestlings: 3 Jul
- High counts: 40+ at Thomas Creek WMA, Keya Paha Co 26 Jun 2016, 30 at Indian Cave SP 30 Jun 2010, and 14 in Sarpy Co 23 Jun 1996.
Fall: summer <<<>>> Sep 20, 23, 24
Migration occurs in late Aug and Sep. “Scores” were heard at Platte River SP, Cass Co 3 Sep 1983 where none were heard 8 Aug; these birds were considered migrants (Green 1984). one was recorded at Ponca SP, Dixon Co 16 Sep 2018 (https://ebird.org/admin/reviewSub.htm?subID=S48558506). Roger Sharpe (personal communication) reported a period of regular fall singing (albeit weak and non-repetitive) in early to mid-Sep in eastern Nebraska and western Iowa; sporadic songs may be heard year-round (Cink et al 2017).
Whip-poor-wills may occur on occasion west of the summer range during fall migration; three were heard in Polk Co 2 Sep 2012, singles were seen at Wilderness Park, Lincoln, Lancaster Co 23 and 24 Sep 2000, and westernmost was one calling in Lincoln Co 8 Sep 2014. This species is a casual migrant in eastern Colorado in May and Sep (Andrews and Righter 1992).
